## Homework Statement

The electric field strength across a typical cell membrane is about 10

^{7}N/C. Given this information, find the magnitude of the acceleration of a single charged Ca

^{+1}ion as it penetrated throught the cell wall. Ignore any resistive forces.

One atomic mass unit is 1.66 x 10

^{-27}kg.

## Homework Equations

F = ma

F=q

_{0}E

## The Attempt at a Solution

I was thinking of multiplying the charge with how many protons a Ca ion has so:

F=q

_{0}E

= (20[itex]\bullet[/itex]1.6*10

^{-19}C)(10

^{7}N/C)

= 3.2*10

^{-11}N

Then I manipulated for acceleration in F=ma and got 1.93*10

^{16}m/s?

Is this the correct method for finding the magnitude of acceleration?
